UNITED STATES WILLIAM B. ORCUTT, OF ROSCOMMON, MICHIGAN.

SEPARATOR.

Application led May 18, 1923.

To all whoml t may concern:

Be it known that I, WILLIAM B. ORCUTT,

a citizen of the United States, residing at Roscommon, in the county of Roscommon and State of Michigan, have invented new and useful Improvements in Separators. of which the following is a specification.

This invention relates to improvements in separators especially designed for separating sand, gravel and stone.

An object of the present invention is the provision of a separator which includes in a single unit, means for separating sand, gravel and stone and for delivering them at separate places.

Another object of the invention is the provision of a separator of this character which is simple and eflicient in use, light and durable in construction and which may be easily transported from place to place.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, 25 illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation of a separator constructed in accordance with the invention.

Figure 2 is a plan view of the same.

Figure 3 is a central longitudinal section.

Figure 4 is a central transverse sectional view.

Figure 5 is a detail view of one of the removable stone and gravel separating elements.

Referring in detail to the drawings, wherein like characters of reference denote corresponding parts, the reference character indicates a frame which may be of any suitable 'construction and which provides bearings for a shaft 11.

`Mounted for rotation upon this shaft is a drum 12 which includes spaced annular members 13 which are connected by transverse bars 14. These members 13 are L- shaped in cross section and are connected by a reticulated wall 15 which provides a screen for the passage of sand. If desired, this wall may be of sectional formation so as to permit of the renewal of Worn or damaged Serial N0. 639,921.

sections. The annular members 13 further include inwardly extending flanges 16 so= that a circular trough is provided for the reception of the material to be separated.

The separator further includes a sleeve or hub 17 which is connected to the drum by radial arms or spokes 18. These arms or' spokes 18 are located to one side of the transverse center of the drum and mounted upon the sleeve or hub 17 and spaced from and. connected to the arms or spokes 18 by means of transverse arms 19 is a circular deector plate 20, whose edges are spaced from the reticulated wall 15. This plate acts as a de- Hector or stop when the material is thrown into the drum.

Secured to the arms or spokes 18 and to the transverse bars 14 are pockets 21, one wall 22 of Which is deflected outwardly. rllhese pockets act to collect the gravel as the drum is rotated and to carry it upward over the horizontal center of the drum and discharge the said gravel into a chute or apron 23 which is supported by the frame.

Also located within the drum at spaced intervals is a plurality of inwardly extend ing inclined fingers 24 which are so spaced as to cause the larger stones to travel upward when the drum is rotated in the direction of the arrow shown in Figure 1. rThe fingers 24 are carried by a base 24a and the latter has a removable engagement with the transverse bars 14, so that any number of these separators may be employed, or, if desired they may be entirely removed when only sand and gravel is to be separated. These stones are deposited upon a relatively coarse screen 25 having a deflected wall 26 which serves to eject the stones when these screens 25 are past the vertical center of the drum, The sand passes through the reticulated wall 15 and is deposited upon a sand belt or carrier 27.

One of the annular members 13 is provided around its periphery with gear teeth 28 which are engaged by a gear `29 which is mounted upon a shaft 30 and this shaft may have mounted thereon a drive pulley 31 which is driven from any suitable source of power. Also meshing with the gear teeth 28 is a gear 32 which is mounted upon a shaft 33 and mounted upon this last mentioned shaft is a pulley 34 over which travels a belt 35. This belt provides a pulley 36 which is mounted upon a shaft 37 and the last mentioned shaft serves to operate the sand belt or lcarrier 27.

It will be apparent Jfrom the foregoing description and accompanying drawings that the invention provides a separator whereby sand, gravel and stones may be eiiectually separated, the sand passing through the re-` ticulated wall l5 and the gravel travelling upward Within and being y discharged through the pockets 21 upon the chute or apron 23, while the gravel is discharged from the screen 25.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within Ithe scope of the appended Claim.'

Having described the invention what is claimed is A separator comprising a rotatable drum includingv spaced annular frames and a reticulated wall connecting the frames, annular flanges extending inwardly from each end of the drum, a deflector wall located between the flanges and havingvits edges spaced from the reticulated wall of the drum, a plurality ot transversely spaced inwardly extending inclined fingers projecting inwardly from the reticulated wall of the drum for separating the stone and gravel, spaced pockets located within the drum for :delivering the gravel, and relatively coarse screens secured to the drurn and delector plate and spaced from thereticulated wall land said screen having deiiected walls serving to ej ectthe stones from the drum.

In testimony whereof 'ln ailix my signaturel` WILLIAM B. ORGUTT.
